33's with out corrected computer..
Well i have a question just as the title states. i have a 2005 ford fx4 off road with 4.10s its lifted and got 33's on it but i have not bought a programer or anything to fix the computer of speed and trans shift points. Because i haven't done this yet how much is it hurting my mpg, performance and towing. Is it worth buying a tru speed from super lift or programer??
does anyone know how much the shift points would be off by?? thanks

My truck is double lifted, same gears, running 33's. I just got an SCT tuner about 2 months ago. It idles smoother, seems to be a little more quiet, but I havent noticed a dramatic MPG change. I do recommend getting one though, just to make the proper computer adjustments and also diagnosing issues on your own. Even though it changed a few minor things, I believe in them and I think its worth the money
